Specification of Letters Patent.

Patented Dec. 24, 1907.

Application filed June 5, 1907. fierial No. 377,371.!

T 0 all whom it may concern:

Be it known that I, AURELIUS B. Mosnn, a citizen ofthe United States, residing at Los Angeles, in the county of Los Angeles, State of California, have invented certain new and useful Improvements in Switch- Stands; and I do hereby declare the following to be a-full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to railway switch stands and has for its object to provide a construction of switch stand of such nature that the condition of the switch will be indicated to the engineer of a train approaching the switch in either direction.

It is a well known fact that the targets employed upon switch stands now in use are unreliable as the lamps are frequently jarred to such an extent that they become extinguished and the signal blades employed are usually made so small as to be visible only when quite near the stand. Furthermore in the present construction of stands it is fre quently. necessary to walk entirely around the stand and onto the track in order to throw the switch and it frequently occurs that while a switchman is so engaged he is struck by the on-coming train.

In carrying out my invention I have provided a stand in which the hand lever is so positioned that it can be swung while the switchman is standing still.

In the accompanying drawings, Figure 1 is a front elevation of a switch stand constructed in accordance with my invention, the signal devices of the stand being positioned to indicate a closed switch, Fig. 2 is a similar view, the signal devices being positioned to indicate an open switch, Fig. 3 is a side elevation of the stand, Fig. 4 is a top plan view, Fig. 5 is a vertical sectional view taken axially therethrough and in a plane at right angles to the plane occupied by the semaphore arm, Fig. 6 is a detail horizontal sectional view taken through the stand directly above the semaphore arm, and, Fig. 7 is a similar view but taken in a plane below the arm.

In the drawings there is shown a main track section 10 and a side track section 11 and a pair of ties 12 upon which the switch points of the side track section are supported, these ties being extended to one side of the said track sections as clearly shown in the top plan view of the drawings and bein designed for the support of the switch stan I which will now be described.

The switch stand comprises a tubular casing 13 which is secured at its base upon the ties 12 as indicated at 14 and extends vertically. A vertically disposed shaft 15 is ournaled at its upper end in a bearing 16 within the casing and is provided adjacent its lower end with a collar 17 which is held thereon by means of a set screw 18 and which rests upon a circular plate 19 secured at the base of the stand, the shaft being extended through the plate and at its extreme lower end through a bearing 20 formed in a cross piece 21 which connects the ties 12. At its extreme lower end the shaft 15 is provided with a right angularly extending arm 22 to which is pivoted the inner end of a switch rod 23, the said rod being connected in the usual manner with the switch points of the side track sectionf l Fixed upon the shaft 15 for rotation therewith is a segmental beveled gear 24 and this gear meshes with a beveled pinion 25 upon a shaft 26 which is journaled in a bearing 27 in the front side of the casing 13 adjacent the base thereof. Fixed to this shaft outwardly of the casing is a hand lever 28 which may be swung substantially in a semi-circle and vertically to rotate the shaft 26 and to impart a turning movement to the shaft 15 as will be readily understood. Formed upon the said front side of the casing 13 or secured thereto in any suitable manner is a bracket 29 includin portions which extend upon opposite si es of the casing and which are provided at their ends with rests 30 for the reception of the hand lever 28 when at either limit of its swinging movement. One of the rests 30 embodies a suitable locking device 31 by means of which the lever may be locked against movement when the switch is closed.

A segmental beveled gear 32 is fixed upon the shaft 15 for rotation therewith at a point to the sha fore described, is adapted to be swung in a vertical plane transversely of the extent of the main track section.

Fixed upon that side of the casing 13 which is presented from the tracks and adj a cent the upper end of the said casing is a lamp bracket 37 for the support of a lamp 38, this lamp being provided with oppositely presented bulls eyes 39. Fixed upon the semaphore arm at the inner end thereof is a bracket 40 including right angularly extending pairs of arms 41 and 42, the arms 41 carrying each red targets 43 and the arms 42 each green targets 44, it being understood that when the semaphore arm is raised, the two red targets 43 will be brought into posi tion one in front of each of the bulls eyes of the lamp and that on the other hand when the semaphore arm is lowered the green targets will be brought into this position.

What is claimed, is

A switch stand of the class described comprising a tubular vertically disposed casing, a shaft mounted vertically within the casing for turnin movement, a crank arm secured f t at its extreme lower end and beneath the base of the casing, a switch rod pivoted to the crank arm, a segmental gear fixed to the shaft for rotation therewith, a shaft journaled in the front side of the casing, a pinion carried by the last named shaft and meshing with the segmental gear, a bracket fixed upon the said front side of the casing and extending to each side of the same, a lever arm secured to the last named shaft, lever rests formed at the ends of the bracket and designed for the reception of the hand lever when at either limit of its movement, a lock associated with one of the rests for locking the lever thereto, a shaft journaled in the front side of the casing adjacent the upper end thereof, a semaphore arm carried by the said shaft, a pinion carried by the shaft, a segmental gear fixed to the first named shaft and meshing with the said pinion, a lamp bracket fixed upon one side of the casing, a lamp supported from the bracket and having bulls eyes which are presented in opposite directions, a bracket secured to the inner end of the semaphore arm and including pairs of right angularly exten ding arms, targets of one color carried by each of the arms of one pair, and targets of another color carried by each of the arms of the other pair, the targets of either pair being adapted to be brought into position in front of the bulls eyes of the lamp.

In testimony whereof, I aflix my signature in presence of two witnesses.

AURELIUS B. MOSER.
